The invention relates to a die for cutting a shape or pattern from a material, the die being composed of a base plate (1) comprising an upper surface (2) and a lower surface (3). The die comprises one or more raised edges (4) in the form of a pattern or shape to be die-cut or embossed, on each of the upper and lower surfaces, such that the die can be used to die-cut or emboss two sheets of material simultaneously.

A heat transfer interface structure and a method of manufacturing the same are disclosed. A substrate has a plurality of raised features formed on at least one surface the substrate. The raised features are deformable under a compressive force and have respective openings at end portions thereof. A thickness of a raised feature at the end portion thereof is smaller than a thickness of the raised feature at an intermediate portion of the raised feature.

In a wrinkling prevention device, a work roll having a diameter smaller than that of a press-roll is pressed against the press-roll, and the work roll is supported by a bearing frame through a backup. With this configuration, an uncoated part can be elongated with a uniform pressing force. Further, an edge roller is disposed at an end part of the bearing frame which supports the work roll, and the edge roller is brought into contact with the other press-rolls not in contact with the work roll so that the axis parallelism of the work roll with the press-roll can be ensured.

The present invention provides an integrated method for forming and performance control of NiAl alloy thin-walled tubular parts. A Ni/Al laminated foil tube is obtained after Ni foils and Al foils are alternately laminated and coiled; and the Ni/Al laminated foil tube is subjected to plastic forming, reaction synthesis and densification treatment in a gas bulging forming die to obtain a NiAl alloy thin-walled tubular part. The present invention solves the problem in the prior art that the preparation of an existing NiAl alloy sheet and the formation of the thin-walled tubular part from the sheet feature difficulty in material flow and structural performance control and a complicated process. Data of embodiments shows that the NiAl alloy thin-walled tubular parts obtained by using the method of the present invention has a high forming rate, high dimensional precision, uniform composition distribution, good tubular part compactness and no defects on the surface.
